2014-2020 Formula One 1.6l V6 turbo engine formula

I just watched a video on permanent magnet vs. induction electric motors and made me think about what kind are used in F1.. does anyone here know?

From what I saw in the video, I guess having both is best case scenario, but I doubt that's the case, so I'm guessing they are using permanent magnet because they can deliver more power at higher speeds.

According to CAR MAGAZINE - (CARMAGAZINE.CO.UK OF 2020) MGU is a permanent magnet brushless AC electric motor.

Audi has their on the benches and running full GP distances.

to not impede gearshifts the MGU-K needs high acceleration/deceleration ability 10000-11500 crank rpm in c.5 millisec
the induction machine can never be responsive enough for this

interestingly the latest plan for 2026 is to continue having 8 speeds (6 was predicted)
the rpm drop being 40% more with 6 speeds it's likely there's a shift response issue (with 6 speed & 2026-size MGU-K)

Does anybody happen to know what method current F1 engines use for their rev limiter(s)?
Just curious after some chat on various broadcasters around Gasly's engine failure.

I had a search but couldn't find anything concrete for the V6 formula.

Depends what you mean by "method".
They would have several options available to them.

• Cut ignition. It is almost certain that Ignition cut is not used - unless fuel is simultaneously cut. Ignition cut alone wastes fuel.

• Cut fuel (skip injection). Fuel cut may be the most efficient. Leaving the throttle and boost in place ensures that firing events that remain are at the highest possible efficiency.

• Intake throttling. Throttling is easy to do - the ECU already has this capability.

Ignition cut or fuel cut would involve cutting ignition or fuel events in some order that shares the cutting over all cylinders. The number of "cut events" would start with a small number at some rpm just below the limit, and progressively increasing to 100% cut at the rpm limit.

Quite the spectacle to see the renault engine die after doing 13K RPM. I would imagine the tolerance levels (strength) is on the limit of engine use range, rather than build a bit stronger for that extra bit of reliability and pushing it harder for longer under certain conditions (strat mode, etc).

I'm so happy they went for an 8-speed. A 6-speed would make these miserably slow cars even slower.
